Which Squarespace plan do I need?
Code Injection is available on the Core, Plus and Advanced plans, and on some legacy plans such as Business. The Basic plan can't add scripts, so it can't run a live chat widget.
Install guide
Squarespace's Code Injection adds a script to every page at once. Paste the Mewdesk snippet in the Footer field and save.

Where it goes
The snippet is the same on every platform: one script tag just before the closing body tag. These steps show where that is on Squarespace.
Add your website under Websites, using the domain you are installing on, and copy the snippet from its Embed code page. It has your site ID filled in; the one shown here uses a placeholder.
In your site's panel open Website › Website Tools › Code Injection, or type Code Injection in the panel's search bar (older menus: Settings › Advanced › Code Injection). Code Injection is included on the Core, Plus and Advanced plans and on some legacy plans; the Basic plan doesn't have it.
Use the Footer field, not Header, so the tag sits at the end of each page. Click Save.
The chat bubble appears on every page straight away. The site preview inside the editor may not run injected code; open your site in a normal tab.
Good to know
What you get
The widget lives in its own iframe, so it looks and works the same on Squarespace as everywhere else.
That is the whole install. No npm package, no build step, no plugin to keep updated.
Visitors see your answer the moment you send it, without refreshing. Your team replies from one inbox.
When nobody is online, visitors leave their email and a message, and the chat picks up where it left off.
No IP addresses, no fingerprinting, no third-party scripts. A name, an optional email and the conversation.
